I have not seen Ricoh presenting any new Pentax lens roadmaps at the 2016 Photokina show. If anyone has seen updated versions, please email me. Here are the last known Pentax lens roadmaps from few months ago:

Ricoh registered a new Pentax K-70 camera with the Korean Radio Research Agency (RRA). My guess is that this new camera will be announced during the Photokina show in September and it will be a replacement for the current K-50 model. Stay tuned for additional details. Via Digicame-info
